Description

  The present invention relates to a package of a disk such as an optical disk (compact disk, mini disk, laser disk, etc.) and a magnetic disk (flexible disk, etc.). More specifically, the present invention relates to a disc package suitable for binding to a book.

  Conventionally, as a disk package that can be bound into a book, the top and middle sheets of the backing sheet, with the top paper, middle paper, and bottom paper bonded together, are cut out to form a disk storage unit. A disc that can be taken in and out of the disc storage unit by covering the disc storage unit with a peelable adhesive and covering the disc storage unit so that the transparent film can be repeatedly peeled and adhered. Is known (see, for example, Patent Document 1).

  In addition, an upper base sheet in which a middle sheet having a rectangular cutout portion larger than the disk and an upper sheet having a circular window opening smaller than the disk at a position overlapping the rectangular cutout portion is bonded, and the size of the disk is almost the same. A sheet of paper with a circular cut-out part and a base sheet that is bonded to the base paper that forms the bottom are bonded together with the discs stored in the circular cut-out part of the base sheet, facing each other, Positions corresponding to two adjacent sides of the rectangular cutout part of the upper paper window that overlaps the rectangular cutout part by enclosing and wrapping the disk in the space formed by the cutout part and the circular cutout part There is known a disc that can be taken out by cutting along a cutting line for opening formed on the disc and folding it (see, for example, Patent Document 2).

  By the way, since the package of patent document 1 has covered the disk with the transparent film, it has the advantage that it can prevent a finger from touching a disk directly while being able to confirm a disk from the outside.

  However, since the transparent film can be repeatedly peeled off and adhered, there is a problem that the disk cannot be removed or replaced when the package is bound in a book and arranged in a bookstore.

  On the other hand, since the package of Patent Document 2 is opened by cutting along the cutting line for opening, since an opening mark remains, it is possible to suppress extraction and to easily find replacement or the like. .

  However, if the cutting along the opening cutting line is not performed carefully, there is a problem that a part of the surface of the mount (the surface of the upper paper) is accompanied by delamination at the time of cutting, and the appearance tends to be dirty. In particular, the surface of the upper paper is often printed with a description of a disc to be stored, a decorative pattern, and the like, and if this surface is delaminated, the explanation cannot be read or the appearance tends to be significantly reduced. In the package of Patent Document 2, the cutting line for opening is formed at a position corresponding to two adjacent sides of the rectangular cut-out part and must be cut across the corner part. There are also difficult problems. Furthermore, since the window for confirming the disc from the outside is in an open state, there is a concern that the merchandise value may be reduced by attaching a finger mark or the like to the disc at the time of display.

  The present invention has been made in view of the above-mentioned conventional problems, and it is easy to prevent the disk from being pulled out or replaced. For the disk package opened by cutting with the cutting line for opening, delamination of the surface of the mount at the time of cutting An object of the present invention is to make it possible to prevent unsealing, and to facilitate the opening operation and to cover and protect the window portion for checking the disk from the outside with a synthetic resin film.

To achieve the above object, the present invention provides a disc storage portion in which the intermediate paper on which the top paper, the middle paper, and the bottom paper are bonded is cut out into a circular shape, and the disc is stored in the disc storage portion. a disk stopper which is attached to the bottom sheet to expose the disc storage portion by fitting the cell pointer over holes are accommodated,
The upper paper has a window opening corresponding to the center of the disk stored in the disk storage section, and the peripheral edge of the window protrudes to the inside of the disk storage section and is above the outer peripheral edge of the disk. The window frame that covers
Further, a transparent synthetic resin film is bonded to cover the entire surface of the upper paper including the window portion, and a circular shape that intermittently penetrates the synthetic resin film and the upper paper along the base of the window frame portion. The present invention provides a disk package characterized in that an opening cutting line is formed.

Further, in the present invention, a part of the synthetic resin film, the upper paper, and the inner paper that are in contact with the outside of the opening cutting line is cut out to constitute a finger hook portion,
A folding slit is formed along one side of the mount, and the outside of the folding slit is a binding margin to the book,
Is included as a preferred embodiment thereof.

  According to the present invention, since the synthetic resin film is bonded to the surface of the upper paper, when the window frame is cut off along the cutting line for opening, the delamination of the surface of the upper paper is the above synthetic resin film. And the window frame portion can be easily and neatly cut off, and it is possible to prevent the description of the disc applied to the upper paper surface and the printing such as the decorative pattern from being cut off when opened.

  In addition, since the cutting line for opening in the present invention is formed in a circle along the base of the window frame portion protruding inside the circular disk storage portion, the propagation of the cut along the opening cutting line is smooth. Easy to cut.

  Further, since the window is covered with a transparent synthetic resin film, the finger does not directly touch the disc before opening, so that the disc can be prevented from being soiled.

  An example of the present invention will be described with reference to FIGS.

  1 is a perspective view showing an example of a disk package according to the present invention, FIG. 2 is a schematic cross-sectional view of the AA portion of FIG. 1, and FIG. 3 is a schematic cross-sectional view of the BB portion of FIG. 4 is a perspective view showing an opening operation state of the disk package shown in FIG. 1, FIG. 5 is a schematic cross-sectional view after opening corresponding to the AA portion of FIG. 1, and FIG. 6 is a BB portion of FIG. It is a typical sectional view after opening corresponding to. In addition, the same code | symbol in FIGS. 1-6 shows the same member or site | part.

  As shown in FIGS. 1 to 3, the disk package of this example uses a mount 4 in which an upper paper 1, a middle paper 2 and a bottom paper 3 are bonded together. Since the top paper 1 and the bottom paper 3 are often printed on the exposed surface, it is preferable to use a coated paper, and the middle paper 2 can be composed of cardboard. Further, the top paper 1, the middle paper 2 and the bottom paper 3 may be formed by laminating a plurality of layers of paper for the purpose of adjusting the thickness.

  The inner paper 2 has a thickness substantially equal to the height of a disk stopper 5 to be described later, and a disk storage portion 7 is formed by circular cutting of a size capable of storing the disk 6. The disk storage portion 7 may be the same size as the disk 6, but is preferably larger than the disk 6 in order to facilitate loading and unloading of the disk 6.

  The bottom paper 3 constitutes the bottom surface of the disc storage portion 7 and is bonded to the lower surface side of the middle paper 2. A disc stopper 5 is attached to the center of the bottom paper 3 portion exposed inside the disc storage portion 7. The disk stopper 5 is for fitting the center hole 8 of the disk 6 to hold the disk 6, and the state where the center hole 8 is fitted and held in the disk stopper 5 in the disk storage portion 7. The disc 6 is stored.

  A window portion 9 is punched in the upper paper 1 at a position corresponding to the central portion of the disc 6 stored in the disc storage portion 7. The window 9 has a circular shape smaller than that of the disk 6, and the peripheral edge of the window 9 protrudes to the inside of the disk storage portion 7 to constitute a window frame 10 that covers the outer peripheral edge of the disk 6. In other words, the disc 6 in the disc storage portion 7 is sandwiched between the bottom paper 3 and the window frame portion 10 of the upper paper 1.

  A transparent synthetic resin film 11 is bonded on the entire surface of the upper paper 1 so as to cover the window 9. As a synthetic resin film, films, such as a polypropylene, polyethylene, polyester, a polyvinyl chloride, can be used, for example. The synthetic resin film 11 is preferably colorless and transparent so as not to be difficult to see when the surface of the upper paper 1 is printed, but a colored transparent film can also be used.

  The synthetic resin film 11 preferably has a thickness of about 15 to 20 μm so as not to hinder cutting along the opening cutting line 12 described later. Moreover, the synthetic resin film 11 can be bonded to the upper paper 1 by laminating using, for example, a transparent aqueous acrylic adhesive.

  The base of the window frame 10 of the upper paper 1 (the portion along the edge of the disk storage portion 7) is composed of slits or perforations that penetrate the synthetic resin film 11 and the upper paper 1 intermittently. A circular opening cutting line 12 is provided. In addition, a part of the synthetic resin film 11, the upper paper 1, and the middle paper 2 that are in contact with the outside of the cutting line 12 for opening is cut out to form a finger hook portion 13. In the illustrated example, two finger hooks 13 are formed at positions facing each other.

  A folding slit 14 is formed along one side (the long side on the left side in the drawing) on which the synthetic resin film 11 is bonded, and the outside of the folding slit 14 is a binding margin 15 for the book. . The folding slit 14 is for facilitating the folding of the mount 4 and opening the page when the disc package of the present example is bound into a book through the binding margin 15, and from the synthetic resin film 11 side. It is formed in the middle of the middle paper 2 or at a depth almost penetrating the middle paper 2.

  The disc package of the present example puts a fingertip into the finger-hanging portion 13, grips and pulls the window frame portion 10, and cuts along the opening cutting line 12 as shown in FIG. Can be opened together with the synthetic resin film 11 part which covers it. After opening, as shown in FIGS. 5 and 6, the disc storage portion 7 is in an open state. Even after opening, the disc 6 that has been taken out has its center hole 8 as a disc stopper 5. By fitting and storing it in the disk storage unit 7, it can be stored without being dropped.

  In the above example, the synthetic resin film 11 is attached only to the surface of the upper paper 1, but the synthetic resin film 11 is also attached to the surface (outer surface) of the bottom paper 3 to adjust the texture of the front and back. Further, it is possible to protect the printing surface when the surface of the bottom paper 3 is printed.

  Next, a method for manufacturing the disk package will be described with reference to FIGS.

First, the bottom paper 3 is bonded to the lower surface side of the intermediate paper 2 from which the disk storage portion 7 and the finger hook portion 13 have been cut out in advance. This bonding can be performed with, for example, a vinyl acetate emulsion adhesive.

  After the middle paper 2 and the bottom paper 3 are bonded together, as shown in FIG. 7B, a disc stopper 8 is attached to the center of the bottom paper 3 exposed in the disc storage portion 7 of the middle paper 2 as an adhesive. Attach with.

  Further, as shown in FIG. 7C, the center hole 8 is fitted into the disk stopper 8 and the disk 6 is stored in the disk storage portion 7. The storage of the disk 6 is usually performed immediately before sealing by bonding with an upper paper 1 and a synthetic resin film 11 described later.

  On the other hand, as shown in FIG. 8A, the upper paper 1 and the synthetic resin film 11 are pasted together by covering the upper surface of the upper paper 1 with the window portion 9 cut out in advance. This bonding can be performed by applying a transparent water-based acrylic adhesive on the upper surface of the upper paper 1 from which the window portion 9 has been cut out, and covering the coated surface with the synthetic resin film 11 and heat-pressing it.

  After the synthetic resin film 11 is bonded, as shown in FIG. 8B, the unsealing cutting line 12 passing through the synthetic resin film 11 and the upper paper 1 intermittently, and the synthetic resin film 11 and the upper paper 1 The finger-hanging portion 13 is formed. The opening cutting line 12 is formed at a position along the outer edge of the disc storage portion 7 formed on the inner paper 2, and the finger hooking portion 13 is formed at a position corresponding to the finger hooking portion 13 of the inner paper 2. Further, a window frame portion 10 is formed between the opening cutting line 12 and the window portion 9.

  The middle paper 2 and bottom paper 3 portions that are bonded together as described above and the disk 6 is stored in the disk storage portion 7, and the upper paper 1 and the synthetic resin film 11 portions that are bonded together as described above are shown in FIG. As shown in FIG. 4, the middle paper 2 and the upper paper 1 are faced to each other, the positions of the finger hooks 13 are matched, and the two are bonded and sealed. This bonding can also be performed with a vinyl acetate emulsion adhesive or the like, similar to the bonding of the intermediate paper 2 and the bottom paper 3.

  In addition, the bending slit 14 shown by FIG.1 and FIG.3 can be formed by giving a half cut from the synthetic resin film 11 side after this sealing.
